Project description:We report the genome sequence of Salmonella enterica subsp. enterica strain Durban, isolated from a patient with salmonellosis and typhoid fever. The strain is closely related to S. enterica subsp. enterica strain P125109 but differs in loss of the SE20 prophage and acquisition of a prophage similar to ELPhiS.
Project description:Salmonella enterica constitutes a group of enteric pathogens with a broad host range, including humans, reptiles, and birds. S. enterica subsp. enterica is a common cause of inflammatory diarrhea in humans. We present the draft genome of S. enterica subsp. enterica serovar Enteritidis strain SEJ, including a 59-kbp plasmid.
Project description:Salmonella enterica subsp. enterica serovar Thompson strain RM6836 was isolated from lettuce in 2002. We report here the complete sequence and annotation of the genome of S. Thompson RM6836. This is the first reported complete genome sequence for S. Thompson and it will enhance our understanding of this serovar and provide another point for comparative studies between Salmonella enterica strains.
Project description:The genome of Salmonella enterica subsp. enterica serotype Senftenberg N17-509, a strain isolated from desiccated coconut, was sequenced using single-molecule real-time sequencing. It consists of a 5.1-Mbp chromosome and a 29-kb linear plasmid.
Project description:Abstract Mango has been implicated as food vehicle in several Salmonella-causing foodborne outbreaks. Here, Salmonella enterica subsp. enterica serovar Minnesota was isolated from fresh mango fruit imported from Mexico in 2014. The complete genome sequence of S. Minnesota CFSAN017963 was sequenced using single-molecule real-time DNA sequencing. Distinct prophage regions, Salmonella pathogenicity islands, and fimbrial gene clusters were observed in comparative genomic analysis on S. Minnesota CFSAN017963 with other phylogenetically closely related Salmonella serovars. Core genome multilocus sequencing typing analysis of all the S. Minnesota isolates in the Genbank and Enterobase also revealed a high genomic diversity among the genomes analyzed.
Project description:The genome of Salmonella enterica subsp. enterica serovar Weltevreden strain 2007-60-3289-1 was sequenced. The genome sequence of this fresh-vegetable isolate from Scandinavia will be useful for the elucidation of plant host factors in comparison to other serovars of S. enterica subsp. enterica.
Project description:In this report, we announce the first whole-genome sequencing of Salmonella enterica subsp. enterica serovar Ouakam strain GNT-01, isolated from ground turkey retail meat. The strain has a chromosome of 5,088,451 bp long, with a G+C content of 52.3%, and a plasmid of 109,715 bp.
Project description:Salmonella enterica subsp. enterica serovar Corvallis is commonly reported in avian populations and avian by-products. We report the draft genome sequence of a multidrug-resistant S. Corvallis strain (NPHL 15376). To our knowledge, this is the first reported case of this serovar isolated from human blood in the United States.
Project description:Salmonella enterica spp. are pathogenic bacteria commonly associated with food-borne outbreaks in human and animals. Salmonella enterica spp. are characterized into more than 2,500 different serotypes, which makes epidemiological surveillance and outbreak control more difficult. In this report, we announce the first complete genome and methylome sequences from two Salmonella type strains associated with food-borne outbreaks, Salmonella enterica subsp. enterica serovar Panama (ATCC 7378) and Salmonella enterica subsp. enterica serovar Sloterdijk (ATCC 15791).
Project description:Salmonella species utilize type III secretion systems (T3SSs) to translocate effectors into the cytosol of mammalian host cells, subverting cell signaling and facilitating the onset of gastroenteritis. In this study, we compared a draft genome assembly of Salmonella enterica subsp. salamae strain 3588/07 against the genomes of S. enterica subsp. enterica serovar Typhimurium strain LT2 and Salmonella bongori strain 12419. S. enterica subsp. salamae encodes the Salmonella pathogenicity island 1 (SPI-1), SPI-2, and the locus of enterocyte effacement (LEE) T3SSs. Though several key S Typhimurium effector genes are missing (e.g., avrA, sopB, and sseL), S. enterica subsp. salamae invades HeLa cells and contains homologues of S. bongori sboK and sboC, which we named seoC SboC and SeoC are homologues of EspJ from enteropathogenic and enterohemorrhagic Escherichia coli (EPEC and EHEC, respectively), which inhibit Src kinase-dependent phagocytosis by ADP-ribosylation. By screening 73 clinical and environmental Salmonella isolates, we identified EspJ homologues in S. bongori, S. enterica subsp. salamae, and Salmonella enterica subsp. arizonae The β-lactamase TEM-1 reporter system showed that SeoC is translocated by the SPI-1 T3SS. All the Salmonella SeoC/SboC homologues ADP-ribosylate Src E310 in vitro Ectopic expression of SeoC/SboC inhibited phagocytosis of IgG-opsonized beads into Cos-7 cells stably expressing green fluorescent protein (GFP)-FcγRIIa. Concurrently, S. enterica subsp. salamae infection of J774.A1 macrophages inhibited phagocytosis of beads, in a seoC-dependent manner. These results show that S. bongori, S. enterica subsp. salamae, and S. enterica subsp. arizonae share features of the infection strategy of extracellular pathogens EPEC and EHEC and shed light on the complexities of the T3SS effector repertoires of Enterobacteriaceae.
